<h3>PARAMETERS</h3>
<dl>
<p>
<dt> <var>memory_object</var> 
<dd>
[in abstract-memory-object (receive) right]
The abstract memory
object port that represents the memory object data, as supplied by the
kernel in a <strong>memory_object_create</strong> call.
<p>
<dt> <var>seqno</var> 
<dd>
[in scalar]
The sequence number of this message relative to the abstract 
memory object port.
<p>
<dt> <var>memory_control</var> 
<dd>
[in memory-cache-control send right]
The memory cache control port 
to be used for a response by the memory manager.  If the memory
object has been supplied to more than one kernel, this parameter
identifies the kernel that is making the call.
<p>
<dt> <var>offset</var> 
<dd>
[in scalar]
The offset within the memory object.
<p>
<dt> <var>data</var> 
<dd>
[in pointer to dynamic array of bytes]
The data that has been modified 
while cached in physical memory.
</dl>
<h3>DESCRIPTION</h3>
<p>
A <strong>memory_object_data_initialize</strong> function is called
as the result of a kernel 
message providing the default memory manager with initial data for a
kernel-created memory object.  If the memory manager already
has supplied data (by a previous <strong>memory_object_data_initialize</strong> or 
<strong>memory_object_data_return</strong>), it 
should ignore this call.  Otherwise, the call behaves the same as the
<strong>memory_object_data_return</strong> call.
<p>
The kernel makes this call only to the default memory manager and only on
temporary memory objects that it has created with 
<strong>memory_object_create</strong>.
<h3>RETURN VALUES</h3>
